.NEAR/SHORT/LONG TERM/...

-- Changed Discussion --
EXPECT CU FIELD ACROSS THE REGION TO DIE OFF QUICKLY TOWARD
SUNSET. THIS WILL ALLOW FOR GOOD RADIATIONAL COOLING. EXPECT
TEMPERATURES TO PLUMMET SHORTLY AFTER NIGHTFALL...WITH MANY
LOCATIONS APPROACHING OR SURPASSING THE FREEZING MARK. WILL ISSUE
A FROST ADVISORY FOR THE SOUTHERN ZONES ALL THE WAY TO THE OCEAN.
COASTAL LOCATIONS MAY BE MODERATED A BIT...BUT SEVERAL LOCATIONS
WILL STILL PROBABLY SEE TEMPERATURES COLD ENOUGH TO PRODUCE A FROST.

LOW PRESSURE WILL TRACK ACROSS SOUTHERN CANADA AND PASS JUST TO
THE NORTH OF THE CWA. THIS SYSTEM WILL DRAG A COLD FRONT WITH IT
AS IT MOVES THROUGH...BRINGING A QUICK SHOT OF QPF TO THE AREA.
THE FLOW ALOFT IS RATHER PROGRESSIVE SO IT SHOULD MOVE QUICKLY OFF
TO THE EAST FRIDAY MORNING. THAT BEING SAID...CYCLONIC FLOW ALOFT
BEHIND THE SYSTEM WILL KEEP INSTABILITY SHOWERS IN THE FORECAST
ACROSS MOST OF THE REGION...ESPECIALLY OVER FAVORED UPSLOPE AREAS
IN THE MOUNTAINS.

HIGH PRESSURE WILL BEGIN TO BUILD IN FROM THE NORTH FOR THE
REMAINDER OF THE FORECAST PERIOD WITH THE NEXT SYSTEM EXPECTED
SOMETIME EARLY NEXT WEEK.
